State police said a tractor-trailer carrying a 31,000-pound excavator was traveling on the Beltway's Outer Loop around 3:30 p.m. Friday when the excavator struck the bridge.

The excavator then landed in the travel lanes of the Outer Loop, spilling dozens of gallons of fuel, SkyTeam 11 Capt. Roy Taylor reported. It took two large tow trucks to move the excavator to the shoulder.

Authorities identified the tractor-trailer driver as 55-year-old Kevin D. McCormick of Hot Springs, Arkansas. McCormick was not injured in the crash.

State Highway Administration officials sent a team of bridge inspectors to inspect the Old Harford Road bridge with a bucket truck.

By 5 p.m., the far left lane of the Outer Loop was getting by the scene. The Old Harford Road bridge over the Beltway was reopened around 5:30 p.m.
